Researchers have discovered that deleting a specific gene in mice prevents them from becoming obese even on a high fat diet, a finding they believe may be replicated in humans. “When fed a diet that induces obesity these mice don’t get fat,” said Prof. James McManaman, Ph.D., lead author of the study and vice-chairman of research for Obstetrics and Gynecology at the University of Colorado School of Medicine. “It may be possible to duplicate this in humans using existing technology that targets this specific gene.” The two-year study, funded by the National Institutes of Health and the U.S. Department of Agriculture, was published last month in the Journal of Lipid Research.
